Nagios Core Reviews

I use Nagios Core for basic monitoring of my systems and services.

What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services.

I have found Nagios Core to be challenging in terms of its centralized architecture and configuration complexities, especially in a Microsoft environment. Making optimizations or changes often requires reinstalling the server, which can be inconvenient.

I have been using Nagios Core for over a year.

It is a very stable product. I would rate the stability as a seven out of ten.

Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers. However, it is scalable in sizing, allowing for easy updates and upgrades without much complication. Just need to adjust settings in the software during the process. I would rate the scalability as a six out of ten.

I have worked with Centreon in my organization as well.

The installation of Nagios Core was relatively straightforward with no major complexities. My team managed to install it within a day. Maintaining it is straightforward for us. We don't do frequent updates; it is a one-time install. The only ongoing task is occasional security adjustments, mainly related to access control. 

I would recommend Nagios Core for CentOS organizations, especially for simpler evaluations or smaller projects where a significant investment isn't required. It is suitable for those without extensive monitoring needs. Overall, I would rate the solution as a six out of ten.

Our primary use case is for Infrastructure monitoring.

Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well.

Nagios Core is very configurable. Whatever you want, you can do it. We have multiple agents and scripts available with the Nagios Core portals and the internet. The cost is also very acceptable.

Datadog provides the compatibility to integrate with these big data platforms like Cloudera and others. These services are very efficient and they provide customer support with it. In this case, I believe Nagios Core will need to provide an option for big data platforms in the future.

I have been working with Nagios Core for the past five or six years.

Nagios Core is highly stable.

Nagios Core is scalable for our purposes.

The implementation was completed in-house because previously it was an open source tool. We can configure it to our own needs, based on our own requirements. The only task we had to complete is creating the script and using the tool. We had alerts created for our mobile phones, email and dashboard.

When we look at pricing version eleven requires purchasing a license. With version seven no license was required since it was open source. When you upgraded to the licensed version only then did you pay for a license

I would rate Nagios Core a nine out of ten.

We mostly use Nagios Core to integrate with Python and Bash Script. If there is a requirement from the client to monitor these services, and Nagios Core does not have the features, we integrate Python and Bash Script with Nagios Core to monitor the services.

Nagios Core does not have a graphic display.

My company has worked with Nagios Core for the last six years.

I rate Nagios Core ten out of ten for stability.

I rate Nagios Core ten out of ten for scalability.

Nagios Core's initial setup was not difficult for me.

Nagios Core is a cheap solution.

Nagios Core is a world-famous open-source monitoring tool. It is easy for us to showcase a Nagios Core demo to the client.

Overall, I rate Nagios Core ten out of ten.

Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs.

Cloud monitoring is an area for improvement because there aren't too many plugins available.

I've been using Nagios Core for almost two years.

It is a stable solution, and I would rate the stability at eight out of ten.

I would rate the scalability at five out of ten.

Nagios Core is an open source solution, and there are no licensing fees.

Nagios Core is a good tool overall, and I would rate it at six on a scale from one to ten.

It's monitoring all of our production environment and alerting us to any issues that might pop up.

The benefits are that it's free and it allows us to monitor all of our production. So it gives us a comfort level of knowing that if there is a problem that pops up, we get notified.

• GUI interface
• Notification capabilities
• Real-time reporting

In terms of any further features, that would bump us into their paid product. For what we get and what we use, and all the libraries that are available, it's pretty robust.

However, for the version we're using, making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do.

It has been rock solid.

So far, it has met our needs. As far as I know, from reading blogs and the like, it can go to many more servers and even multiple data centers. It seems like it's pretty scalable.

Tech support has been pretty good. There have been a couple of occasions where we've had to pick up the phone and call, and for the most part, they are very prompt, very quick, very responsive.

I had used this solution before and there wasn't anything in place here that was any good, so it was a no-brainer for me.

My most important criteria when selecting a vendor are 

• flexibility
• supportability
• scalability.

I set the whole thing up. It wasn't complex, it was just that I had to do a lot of planning. If you follow your plan then you won't end up in trouble. If you deviate from the plan, you are going to have trouble.

We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it. That is something that we wrote and implemented as a plug-in.

I would rate this solution a nine out of 10 because it's relatively easy to implement and the cost is great, it's free.

My advice would be, save yourself a lot of time - go get it and install it.

Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost. However, when implemented correctly, this is a powerful enterprise toolset. Specifically, Nagios provides massive flexibility in terms of the types of endpoints you want to monitor (infrastructure, rudimentary application, process, and storage) and a wide variety of conditions to evaluate across including binary type conditions analysis (like threshold exceeded or not) or degrees of conditions violations (such as 30% warning; 80% critical). The dashboarding and heads up display is practical and useful for enterprise/network operations center use cases. The extensibility of Nagios also allows for integration to ticketing systems further adding value for service support and production monitoring use cases. 

• Low cost approach for massive scale infrastructure monitoring
• Rapid deployment, if you know what you are doing you can have a solid Nagios implementation up and running in short order
• Accurate and actionable information 
• Ability to fine tune alert and condition management engines

Dashboards and HUDS could use a facelift to be more in line with next generation monitoring tools that really have amazing UI’s. Sadly, many people may think that Nagios itself as a tool may not be sophisticated because it lacks the typical definition of a sophisticated UI.

Nagios has significant capability and opportunity for customizations to really “dial-in” the implementation to suit your specific enterprise requirements. But, enabling many of these capabilities requires an SME and to sustain and support the implementation requires effort and manpower. The larger the implementation and more extensive the customizations- the more resource intensive the deployment will become.

Application level monitoring is limited.

To really maximize the power of Nagios, you need an SME (but true if anything in IT).

Our primary use case is for monitoring the security of our environment. We have specific services running on our Windows systems and Nagios provides us with notifications regarding the status, whether things are running properly or not. Sites hosted on IIS can also be monitored. We are customers of Nagios and I'm an infrastructure lead. 

The value of the solution is that we get timely notifications if there are any issues and they can be solved immediately. Nagios provides all the plugins required. 

The UI is a little outdated so it's not as user-friendly as it should be and the graphics should be displayed in a better way. 

I've been using this solution for six years. 

The solution is stable and reliable. 

Because the solution is open source, there's no direct support from Nagios. We post our questions to the community and that provides sufficient support. 

The initial setup is easy and straightforward. Deployment probably took us an hour or two and was not implemented all at once. New areas come up all the time that require monitoring so we research which plugin will be useful and implement that. It's enhanced gradually whenever we have a specific requirement. The implementation was done in-house. There is some maintenance involved, including for the upgrades. I manage the solution but there's a development team to monitor the services, around eight to 10 people. 

The product is open source so it's completely free. It's deployed on an Amazon server so we pay a small amount, maybe $30 per month, for the AWS hosting.

We tested ManageEngine and another open-source product that is an OS but we found Nagios easier to set up and manage. 

I recommend this solution because it's very easy to use. There are good resources available online and we can do everything we need.

I rate this solution nine out of 10. 

We are using Nagios Core mainly for servers. We check the network hardware connectivity. We check for the availability of the network and for hardware failures.

We have deployed Nagios Core on a VM and it's working very well. The specs of the VM are very low because it doesn't require so much storage

The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good.

Nagios Core can improve the graphical interface, it would make things a little easier.

I have been using Nagios Core for approximately five years.

The stability of Nagios Core has been good in our usage.

Nagios Core is scalable for our needs. We don't have many servers and network activity, we have approximately 200 nodes, and it's fulfilling our requirements.

We do not have plans to increase our usage of the solution this time but maybe in the future.

We do not have support for this solution, it is free.

I have not used another solution previously.

The initial setup of Nagios Core is not complicated, once you are used to it, it can be easy. The full implementation took us approximately three hours.

I rate the initial setup of Nagios Core a three out of five.

We maintain Nagios Core in-house.

We are using the free version of Nagios Core.

I have evaluated other solutions.

This solution can meet basic requirements. If someone is using it on a larger scale they might have difficulty managing it.

I rate Nagios Core a seven out of ten.
